Try a mix . All non-AAMC VR books have their faults. If you use a couple different test prep companies, in addition to AAMC stuff, you'll probably have plenty of material. IMO, TPR is second best to AAMC. AAMC offers practice VR passages in the self assessment, the Guide to the MCAT, and in practice tests. Feel free to reuse any AAMC passages you've already taken so you stay use to their style. The self assessment is particularly good for that.
